Canon G7X mk2 Filter Adaptor 52mm

thingiverse

This is specifically designed for the Canon G7X Mk2. With some gentle sanding, it should fit snugly around 52mm filters. You can screw one on first, then add others to that one. Mounting accessories directly to your lens on these cameras isn't exactly elegant, but having a polarizing filter or UV filter is definitely worth the hassle. Make sure not to overtighten it on the camera side - you don't want to damage your lens. It's also a good idea to attach this with a string tied to your wrist strap so you won't drop your filters. Use at your own risk.
